You mention you replaced the DB9's from the EZ G540 db9's? Did you install a current set resistor? Is your estop connected to the G540? Not just an estop thru Mach is it? I personally like a contactor but some act like smaller machines don't need it. Due you have the charge pump enabled? This will stop any motion from occurring if the computer is not on or Mach isn't running though the machine is on IIRC.

Thanks all  for the help

Yes I have the right resistor for each DB9 and all motors run good but have to tune them properly

The E-stop is connected to G540 as it should and it works, I just don’t get the interface I’m used to with Mack (pressing E-stop Mack needs reset)

Charge pump is also enabled

You are not having to press the reset button within Mach after physically pressing an Emergency switch hooked directly to your G540? What version of Mach are you running? Have you updated it lately and possibly installed a version that might have a bug?

Do you have an input pin set in Mach for the E-Stop? Does the G540 pass that to Mach?

My Mach version is R3.043.022 and all is fine now after I downloaded the XML from Gecko; this fixed the problem with the E-stop

BTW why I don’t get an email notification from my post although I have checked the "Notify me of replies" button?

The top of my table (that’s where I will put my pcs for cutting) is 41.5”x 27.5” and I plan to cover it with one of these materials:

3/8” Thick MIC-6 Tooling Plate, $630.00
3/8” Thick Aluminum Plate, $390.00
1/4" Thick Aluminum Plate, $265.00

The first two are too expensive for me and I’m thinking to go with the 1/4" Aluminum plate. The span is not that big and if I put a longitudinal support underneath I feel that’s it should be ok.

What is your opinion?
